How to lift large centrifugal pumps inside the equipment
Thread Content
There are many larger centrifugal pumps inside the device; it’s very difficult to operate them manually. Moreover, when using chains, the pipelines get in the way, and it’s not possible to hang the pumps on those pipelines. I would like to ask the experts: how does your company handle this issue? Are there any effective lifting tools available? It would be great if diagrams could be provided
1. Ease of maintenance should be taken into account during design； Think more carefully about the equipment layout ； Our company is organized in such a way that the pumps are all located in one row ； The motors of the reaction vessels are arranged in two rows ； Areas where manual hoists are installed at the top are equipped with tracks, and areas that need to be removed frequently also have places designated for hanging manual hoists ； This makes it easier to lift and transport the equipment during repairs ； 2. Consider using a tripod with a pulley
It depends on how heavy it is and whether crane lifting is possible; it’s also advisable to include pictures. The situation on site can be complex, so it’s not possible to give a general answer. For weights of 1-2 tons: scaffolding is usually used, along with 2-3 hoists of 1-2 tons each. The first hoist is used to lift vertically, while the second hoist pulls while releasing the first one – repeating this process. If that doesn’t work, another hoist can be added to lift the load out, after which it can be removed using a hydraulic truck or forklift. For weights of 3-5 tons, it’s best to use a crane if available; otherwise, if there are pipelines in the way, it’s necessary to check whether there’s an I-beam frame that can support those pipelines. If such a frame exists, a 5-ton hoist can be used, with the load being lifted using the same method as before. If there’s no I-beam frame and the upper layer is made of concrete, 1-2 holes can be drilled to allow the hoist to lift the load out；
